I followed the recommendations of others to order up a size and they were way too big for me. Too wide and too long. I was excited they were water proof but they reminded me of snowy weather shoes. I did not care for the look of them. I ended up returning them and hoping a different shoe totally will fit my needs.

The upper is made of nylon, the lining is synthetic tricot, and it has a waterproof membrane. It will hold up to repeated soaking and drying. The sole is rubber and should perform well on rocks.
